ADVERTISING OR DISPLAY DEVICE.

SPECIFICATION forming part of Letters Patent No. 429,893, dated J une10, 1890.

u Application filed October 7,1889. Serial No. 326,280l- (No model.)

To all whom, it may concern:

Beit known that I, ANDREW DAHLsTRoM, residing at Ashton, in the countyof Osceola and State of Michigan, have invented cert-ain new and usefulImprovements in Advertising or Display Devices, of which the followingis a speciication.

My invention relates to an advertising or display device more especiallydesigned for use in the dining-rooms of hotels or dwellings and it hasfor its object to provide a suitably-constructed device of thischaracter which may be constructed in the shape of a caster or beconnected with a revolving table.: or a revolving platform used forexhibiting articles of merchandise, dac.

To this end my invention consists in certain novel features ofconstruction and peculiar combination of parts, all of which will behereinafter fully described in the annexed specification, andparticularly pointed out in the claims, reference being had to theaccompanying drawings, in which- Figure l is a side view of myimprovement. Fig. 2 is a central vertical section thereof. Fig. 3 is atop view with the upper or cap lplate removed. Fig. 4 is a detail viewof the tension device hereinafter referred to, and

Fig. 5 is a horizontal section taken on the line 5 5 in Fig. l. 1

In the construction shown I have representedmy improvementin the form ofa caster for dining-tables; but I desire it understood that my improveddisplay devices may be used in connection with and operated by anyhorizontally-disposed revolving platform. In' the drawings, A indicatesa revolving platform, preferably of circular form, and which I shallterm the caster-platform, as this platform forms the support for thevarious cruets, said platform having apertures a a near its periphery,in which the bases of the cruets b b fit. This platform is provided atits center with a depending stem orlug A the upper end a of which isextended above the platform, reduced, and made non-circular incross-section, as clearly shown in Fig. 5 of the drawings. A

The stem A which is centrally apertured, as at A2, seats in a socket B',formed in a supporting-standard or foot-piece B, said socket of the baseO', the column O2, the enlarged y circular casing O3, and the top or capC4.

D denotes a tubular shaft journaled in a central opening C5 in thecolumn Czand base C', which is provided with a hollow non-circular headC(i at its top and is provided with a non-circular open end D2, whichfits the noncircular extension c of the stem A', as clearly shown inFig. 2 of the drawings.

The circular casing CS is formed of the baseplate l and the circularvertical rim 2, which is provided with a series of sight-openings 3 3,through which the scriptural text, bill of fare, picture, the., mayreadily be seen. A glass rim 5 is placed inside vertical rim 2,- asshown.

In connection with the display-case it is desired to arrange theadvertisement on an endless tape or ribbon, which ribbon is to have itsobjective parts so arranged that the partial revolutions of said tapewill cause the various object7 sections on the tape to pass in eitherdirection from one sight-opening to its next succeeding opening. To thisend I arrange a central core (i, made of wood or other suitablematerial, provided with a central metallic tubular hub 7, provided witha non circular projection 8 at its lower end, which engages thenon-circular hollow head O0 of the shaft D.

E denotes an endless tape or ribbon, which is looped around the core 6,its oppositelyextending portions e. e being looped about a series ofrollers 7 arranged in a circle within the rim, as most clearly shown inFig. 3 of the drawings. One of the guide-rollers 7 n is of a` largerdiameter than the remaining rollers 7', one face thereof being arrangedto bear against one side of the core 6. The object of arranging theroller 7 to bear against the core 6 is to form a suitable tensionwhereby the ribbon will positively move when said core is revolved. Tothis end I pivot the lower end of the shaft 7 b, on which the roller 7turns, to the bottom of the casing, as shown at IO.

F denotes a circular disk, which is -pro- IOO vided with a centralaperture f, which receives the extension of the hub, and with a seriesof apertures f which form the bearings for the upper ends of the shafts7 of the rollers 7', and an elongated opening f2, in which the upper endof the shaft 7b extends, said upper end being normally forced toward thecore by means of a spring-wire G, secured to the lower face of the diskF, as clearly shown in Fig. 4. of the drawings.

The top or cap plate C4, which [its over the top of the easing, is heldthereto by a lug h and a spring-catch I, (see Fig. 2,) said top beingprovided with a collar or extension Il, having a central aperture h.

The several parts are securely held together by a rod K, which passesdown through the several central apertures (which form a continuousaperture) and is held in place by means of a nut 7c at its lower end,while its upper end passes up through the cap-plate C4 being providedwith a squared portion k2, engaging a squared end h3 of the opening 7L,its outer projecting end being screw-threaded at 7a4, upon which isscrewed a suitably-ornamented securing-nut J.

From the foregoing description, taken in connection with the drawings,it will be seen that as the platform A is turned the tubular shaft Dwill be revolved, and said shaft, engaging the core 6 in the mannerdescribed, will cause it (the core) to turn, and the tension devicecausing the endless tape to bear against said core will cause it (thetape) to turn, thereby changing the several objective points of the tapein a manner as will be readily understood by reference to the drawings.By arranging the several parts as described they are so adjusted thatthey will turn with a minimum amount of friction.

My invention. is exceedingly simple and novel in construction, cheap asto cost, and effectual for its desired purpose.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

l. The combination, with a revolving platform having a non-circularcentral projection a', of an advertising or display' casin g mounted onsaid platform, a revolving core (3, carrying the said advertisements ordisplays, and a tubular shaft mounted in said casing, having anon-circular end engaging the projection a and connected at its upperend to the core 6, substantially as and for the purpose described.
